\"\"<\/td>\n<\/tr>\n
Generate different size and sharp spherical glass lens by proper process, widely used in various lens unit and lens module.<\/td>\n<\/tr>\n
\u30fbThe whole process can be finished in Sunny, the machines of each process are domestic advanced.
\n\u30fbStable techinical engineers, especially for grinding which accumulated 30 years' technology deposition.
\n\u30fbGrinding: Multichip honeycomb tool grinding, Three jaw grinding process, Soft material, Large diameter process
\n\u30fbCentering: High-precision NAKAMURA-TOME AUTO centering machine, can produce deformed lens, lens element with steps on the rim.
\n\u30fbCoating: can produce vehicle-mounted waterproof flim, UVIR film etc.
\n\u30fbGluing, Painting: can glue the lens with diameter about 60mm
\n\u30fbGrinding: Clip type, Multichip three jaw type.
\n\u30fbCoating: waterproof film, UVIR FILM
\n\u30fbCentering: deformed lens process.
\n\u30fbGluing: Illumination uniformity process<\/td>\n<\/tr>\n
